Cognitive ability, measured by intellectual quotient or IQ, has been thought to predict response to intervention, social abilities, adaptive behavior and long term outcome. Numerous studies have shown that it can influence what is labeled as a good outcome. However, two studies this week point out how those across the spectrum in cognitive ability still benefit from early intervention and make friends on the playground. In both studies, there were factors that were more important for outcome than IQ. So it may be an important factor in outcome, but not the only factor.
